populating listbox with expression, ignoring values

[Anonymous]

I'm creating a list box from an expression that I'd like to be populated with the same values regardless of the selection. Somehow the set analysis qualifier {1} doesn't work.

=aggr(

  //minstring({1<Role={"*"}>}

    if(sum({1}TeamAllocation*ClientAllocation)>0,Role)

  //)

,Role)

I tried using minstring as replacement for only(...) suggested elsewhere.

Any recommendations?  Thanks!
